It turns out our manual locale cleanup is causing issues (see I54490b17a7f8b2f977369044fcc6bb49cc13768e). Upon further investigation, I think this is a better approach than manually deleting repos. glibc on Fedora obeys the %_install_langs macro for reducing the installed locales (as mentioned in the comments, F24 has moved to having different packages, but worry about that later). So our existing clear-out is really only required for CentOS, whose glibc does not have any way to indicate to build less locales. However, %_install_langs is still correct there, as it restricts some of the translation files and other things installed with the %lang macro in spec files. This is complicated by us having to set this at glibc-common install time, which happens with the "yum" from outside the chroot (i.e. on trusty). Since this is too old to have flags to pass this, we need to fiddle with rpmmacros. I've tested this with fedora-minimal builds and the locales file is about 2MiB, which is what it was after the cleanups, and the listed locales are only those we expect (i.e. it appears to be working).
